Steel mesh for steel reinforced concrete slab

ABSTRACT

A steel mesh for steel reinforced concrete slab is disclosed to have a plurality of locating blocks selectively fastened to the ends of steel wire rods thereof to facilitate positioning in a mold accurately and positively during molding with concrete to form a steel reinforced concrete slab.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a steel reinforced concrete slab and more particularly, to a steel mesh structure for steel reinforced concrete slab.

2. Description of the Related Art

A regular steel reinforced concrete slab 1, as shown in FIG. 1, has a steel mesh 2 embedded therein to reinforce the structural strength. During fabrication of the steel reinforced concrete slab 1, as shown in FIGS. 2˜4, a steel mesh 2 is put in a mold 3, and then concrete is poured in the mold 3, and the desired steel reinforced concrete slab 1 is obtained when the applied concrete is hardened. According to this steel reinforced concrete slab fabrication method, the steel mesh 2 may be biased when the concrete is been poured into the mold 3. Thus, the steel mesh 2 may be not accurately kept at the center of the finished steel reinforced concrete slab 1, lowering the structural strength.

SUMMARY OF THE INVENTION

The present invention has been accomplished under the circumstances in view. It is one object of the present invention to provide a steel mesh for steel reinforced concrete slab, which can be kept at the center accurately during molding of the desired steel reinforced concrete slab.

To achieve this and other objects of the present invention, a steel mesh for steel reinforced concrete slab has a plurality of locating blocks selectively fastened to the ends of the steel wire rods thereof. Further, each locating block has an eccentric plug hole for receiving one end of one steel wire rod tightly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring to FIGS. 5˜7, a steel mesh for steel reinforced concrete slab in accordance with the present invention is shown comprising a plurality of steel wire rods 10 transversely and longitudinally welded to one another and a plurality of locating blocks 11 selectively fastened to the ends of the steel wire rods 10. Each locating block 11 has a plug hole 12 for receiving one end of one steel wire rod 10 tightly.

When using the aforesaid metal mesh to make a steel reinforced concrete slab, the steel mesh is put in a mold 3. At this time, the locating blocks 11 support the steel wire rods 10 positively at the center of the cavity of the mold 3. Thereafter, prepared concrete is poured into the mold 3. Subject to the positioning effect of the locating blocks 11, the steel wire rods 10 are kept in position when the concrete is been poured into the mold 3. When the applied concrete is hardened, a finished steel reinforced concrete slab 13 that has the steel mesh of the locating blocks 11 and the steel wire rods 10 embedded therein at the center is obtained.

Further, the plug hole 12 of each locating block 11 can be disposed at an eccentric location so that the locating blocks 11 can be rotated relative to the respective steel wire rods 10 to adjust the elevation of the steel mesh in the mold 3 during fabrication of a steel reinforced concrete slab.

Although a particular embodiment of the invention has been described in detail for purposes of illustration, various modifications and enhancements may be made without departing from the spirit and scope of the invention. Accordingly, the invention is not to be limited except as by the appended claims. 

1. A steel mesh for steel reinforced concrete slab, comprising a plurality of steel wire rods transversely and longitudinally welded to one another and a plurality of locating blocks selectively fastened to the ends of the steel wire rods.
 2. The steel mesh as claimed in claim 1, wherein each said locating block has an eccentric plug hole for receiving one end of one said steel wire rod tightly.
